Chapter 1
In the middle of a war, a transport plane carrying a group of English boys from Britain was shot down over the ocean and it crashed in thick jungle on a deserted island. Scattered by the wreck, the surviving boys lost each other and cannot find the pilot. The story starts with Ralph who meets with a chubby boy named Piggy. Ralph and Piggy look around the beach, wondering what has become of the other boys from the plane. They discover a large cream colored conch shell, which Piggy realizes could be used as a kind of fake trumpet. He convinces Ralph to blow through the shell to find the other boys. The boys were summoned by the blast of sound from the shell and they staggered onto the beach. The oldest among them are around twelve and the youngest are around six. Then a choir led by Jack shows up and all the assembled boys decide to elect a leader or Chief. Ralph is elected chief but with serious opposition from Jack and in order to satisfy Jack, Ralph appoints Jack and his choirboys as the hunters of the "tribe." He then takes Simon, and Jack to explore the island. They find a mountain and explored the land and they return to the beach.
Chapter 2
Ralph returns and tells everyone that the island has no adults that all have to learn to live together. They also agreed on meetings whenever the couch is blown and that, at meetings, the conch shell would be used to determine who has the right to speak. The boy holds the conch shell will speak, and the others will listen silently until they receive the shell in their turn. Even Jack agrees with this idea. Then one of the little kids claims that he saw a "beastie" on the island, which puts fear and scares everyone. Ralph tells the group to build a large signal fire on top of the mountain on the island so that any passing ships might see the fire and know that someone is on the island. Piggy tries to reason with the group about survival but they all ignored him.
Chapter 3
Jack follows and tries to kill a pig but he fails. He returns and finds that Ralph is busy with building the hut with Simon. Ralph is annoyed that boys are unwilling to work on the huts and Jack promises Ralph that they will have better luck with the pig next time. Ralph implies that Jack and the hunters are using their hunting duties as an excuse to avoid the real work. Jack responds to Ralph's complaints by commenting that the boys want meat. Jack and Ralph continue to bicker and grow increasingly hostile toward each other. Simon goes off by himself and finds a place where he can peacefully stay.
Chapter 4
The little kids now called "Littluns" plays all day long and at night has frightful experiences. Ralph is worried about this. The large amounts of fruit that they eat cause them to be sick in the stomach and get diarrhea. Roger and Maurice torture little kids by destroying their sand castles. Jack who is obsessed with catching a pig goes off with his hunters to get a pig. While they were gone, Piggy and Ralph spots a ships that passes by and finds that while the boys were out for the hunt, the fire on the mountain went out ending with the ship passing by without their rescue. Ralph is angry but the boys brought the pig back from the hunt and roasted it and gave it to everyone. Jack is now resenting Ralph and his leadership.
Chapter 5
Ralph goes to the beach and calls a meeting in order to bring the boys into line. Ralph tells them about their failure in duty and that they should do their duty. Ralph also tries to tell the young boys that there is no beast and that they should not be afraid but it failed. The little ones say that the beast hides at day and at night come out of the ocean to haunt the kids and that these kids are in danger. Suddenly, Jack proclaims that if there is a beast then he and his hunters will hunt it down and kill it. Then the group breaks away while Ralph tells Piggy and Simon that he might cease this leadership but they tell Ralph that he need to be leader or Jack might go on a rampage.
Chapter 6
In the darkness, military planes fight in the air above the island but the boys were sleeping so they miss it and they also miss when a parachute lands with a dead person onto the island. When Sam and Eric woke up, in the flickering firelight, they see the twisted form of the dead parachutist and mistake the shadowy image for the figure of the dreaded beast. They rush back to the camp, wake Ralph, and tell him what they have seen. Ralph immediately calls for a meeting, at which the twins reiterate their claim that a monster assaulted them. They look for the monster and when they get to the place where they did not explore the island, the boys start to play around so Ralph gets angry with them.
